So, how much more can you expect to shell out for a jar of peanut butter? That will depend on your favorite label, but all the leading companies plan significant jumps, including Kraft, owners of the Planters brand (40 percent), Peter Pan makers ConAgra (20 percent), and J.M. Smucker (30 percent).

Much as consumers might grumble about the higher prices, in this case it’s a simple matter of supply and demand. This year’s poor harvest has spiked the cost of a ton of peanuts, sending it from $450 a year ago to almost $1,200 this month.

Unfortunately, industry insiders don’t see any relief in sight. Chris Brand, a spokesman for the Giant food chain, admitted that the “outlook does not look good until next year’s crop is harvested and produced.” Publix spokesperson Maria Brous admitted that she expects further food price increases “as the cost of goods continue[s] to rise.”
